BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to a water-containing structure of a faucet control valve and, more particularly, to water-containing structure of a faucet control valve for simplifying assembly, to thereby effectively achieve the purpose of quickly assembling, simplifying the process and reducing material costs.

2. Brief Description of the Related Art

The structure of a general hot and cold mixer faucet (as shown in FIG. 1 and FIG. 2) mainly comprises a body 10, a control valve 14 and a control handle 16, wherein the body 10 is consisted of an upper cylinder seat 11, a rotation seat 12 and a water-impermeable seat 13; the water-impermeable seat 13 is placed inside the body 10, the top side 130 of the water-impermeable seat 13 is used to link the control valve 14, the control valve 14 is fixedly fastened to the upper cylinder seat 11 by using a gland 151 and a bonnet 152, two inlet columns 142, 143, an outlet hole 145 and at least a positioning column 144 are set on the bottom of the control valve 14, the control valve 14 has a lever 141 linking the handle 16 for controlling the flow of the water in and out; two inlet holes 131, 132, an outlet hole 133 and at least a locating hole 134 are set on the top side of the valve seat 13, wherein a water outlet 139 and a lateral hole 135 are set on the middle section, and two guide holes 137, 138 and two retaining bolt holes 136 are set on the bottom, the two guide holes 137, 138 are provided for setting the connector 181 of two inlet tubes 18, the two retaining bolt holes 136 are provided for fastening the two corresponding fixing bolts 19 and fixing the faucet in the installation location by using two fixing pieces C1 and two fixing nuts N1. Basically, there is no major problem when using the abovementioned structure, but the manufacture of the water-impermeable seat 13 has plagued the industry. Since the size of the water-impermeable seat 13 is large, it consumes copper a lot, the cutting, tapping and drilling procedures are complicated during processing, once one of the holes is in error, the whole water-impermeable seat 13 becomes a waste product, especially in the recent years, the price of raw materials increased dramatically, defective products produced in manufacturing processing have formed a heavy burden on the manufacturing cost. Besides, in some faucets without setting a water-impermeable seat inside the body, a water-impermeable board is remained inside the body. When assembling, fastening the water-impermeable board to the inlet tube first, and then attaching the control valve to the surface of the water-impermeable board. In such structure, the process is also complicated, and a very thick material is needed to be remained as the water-impermeable board. If the processing hole is inaccurate, the whole body may become a waste product and the loss may become a heavy burden for the manufacturers. Thus, how to simplify the producing procedure of the body 10 and lower the defect rate may become an urgent problem to be solved for the industry.
